Summary
Distal fifth metatarsal chevron osteotomy using a poly-p-dioxanone (PDS) pin effectively corrects bunionette deformity. This reliable technique ensures adequate fixation and patient satisfaction with minimal complications.
Area of Science:
- Orthopedic Surgery
- Podiatric Surgery
- Foot and Ankle Surgery
Background:
- Bunionette deformity, also known as tailor's bunion, can cause significant pain and functional impairment.
- Traditional surgical interventions for bunionette deformity have varying success rates and complication profiles.
Purpose of the Study:
- To evaluate the efficacy and reliability of distal fifth metatarsal chevron osteotomy with a poly-p-dioxanone (PDS) absorbable pin for correcting symptomatic bunionette deformity.
Main Methods:
- A retrospective review of 12 distal fifth metatarsal chevron osteotomies performed on 10 patients with symptomatic bunionette deformity.
- Fixation was achieved using a single, nonpredrilled PDS absorbable pin.
- Clinical and radiographic outcomes, including union, complications, and AOFAS scores, were assessed.
Main Results:
- All 10 patients achieved clinical and radiographic union by 6 weeks post-surgery.
- No evidence of osteolysis, displacement, or avascular necrosis of the metatarsal head was observed.
- The average postoperative American Orthopaedic Foot & Ankle Society (AOFAS) score was 93/100, with all patients reporting satisfaction.
Conclusions:
- Distal fifth metatarsal chevron osteotomy utilizing a single PDS absorbable pin is a reliable and effective surgical technique for symptomatic bunionette deformity.
- This method provides adequate fixation and a low complication rate, leading to high patient satisfaction.
